Title: Improvements in or relating to radio direction finding installations
IPC: G01S1/02
Filed: 1937-05-27
Abstract: 474,015. Directive wireless signalling. TELEFUNKEN GES. FUR DRAHTLOSE TELEGRAPHIE. May 27, 1937, No. 14752. Convention date, May 27, 1936. [Class 40 (v)] Relates to radio direction - indicators of the kind in which a frame aerial is rotated in synchronism with a glowlamp, the latter being energized by the incoming signal so as to give a constantly-visible bearing line. The invention consists in the provision of a blocking circuit designed to separate a desired signal from interfering ones. As shown in the Figure, the aerial R and glowlamp indicator G are rotated synchronously, and the pick-up signals are fed through an amplifier E and note-frequency filter F to the glow-lamp. A local oscillator O controlled by an auxiliary aerial HA feeds impulses of the same frequency as the desired signals to a valve forming part of the filter circuit F. Or a locally-produced heterodyne note may be used for the same purpose. The impulses serve to remove a prohibitive bias from the valve so that the filter is opened to pass the desired signals but not the others.

Abstract: 401,987. Train-axle-counting apparatus. VEREINIGTE EISENBAHN-SIGNALWERKE GES., Siemensstadt, Germany. May 24, 1933, No. 15065. Convention date, June 4, 1932. Addition to 372,436. [Class 105.] The axle-counting device described in the parent Specification has condensers arranged in series with the pole windings of the step-bystep motor. Figs. 3 and 4 show a form in which a permanent magnet 9 holds the armature 5 in line with the pole windings 10, 11. A passing axle simultaneously closes contacts 2, 1 whereby windings 20, 21 are energized by a current pulse to a condenser 6 and move the armature 5 into line therewith, the holding effect of the permanent magnet 9 being neutralized by the current pulse to windings 10, 11 and condenser 7. The axle then closes contacts 4, 3 before opening contacts 2, 1 and thus the windings 30, 31 are energized to move the armature further. When the axle finally leaves the contacts the condenser 7 discharges through the windings 10 and 11 and resistance 17 ; this current being reverse to the charging current assists the permanent magnet 9 and pulls the armature into the 180‹ position. In another form the permanent magnet affects all the poles so that the armature is held in the position to which it was last moved by a current pulse-energizing a pole pair ; in this form the condenser 7 does not discharge through the windings 10, 11 and the contacts 1, 2, 3, 4 are operated in sequence. The contacts 1, 2, 3, 4 may be controlled by induction impulses arising at the passage of the wheels.

Abstract: 591,586. Drift indicators for aircraft. BENDIX AVIATION CORPORATION. Aug. 9, 1944, No. 15176. Convention date, Aug. 28, 1943. [Class 97 (ii)] [Also in Group XL] The drift angle of an aircraft is measured by comparing the phase of reference waves and waves of identical frequency but of a phase dependent on the drift angle, the two wavetrains being applied to a multiphase motor to cause the motor to operate to produce an indication when a drift angle exists or changes. In the arrangement shown, the multiphase motor 20 has a reference phase winding fG fed from a generator 16, 17 driven by motor 15, the stator 17 being rigid with the rotor of 20 and carrying pointer 21 which moves with reference to scale 22. A further phase winding fA of motor 20 receives waves developed in the output of photo-cell 24 upon rotation of a grid 12 driven by motor 15 and interrupting light passing to the cell 24 from an image of the ground over which the aircraft is flying. Filter 27 selects the appropriate frequency from the output of the cell and the phase of the waves fed to fG varies with the drift angle causing rotor 20 to move till stator 17 is in such position that the waves in the two windings of fA, fG are in phase, whereupon the magnitude of the drift angle is indicated.

Abstract: 611,982. Impedance transformers. HAZELTINE CORPORATION. May 22, 1946, No. 15536. Convention date, June 5, 1945. [Class 40 (viii)] [Also in Group XL (c)] A circuit connector for connecting a balanced and an unbalanced circuit has two sections of equal characteristic impedance. The inner and outer conductors of the connector each comprises two sections, the second section of the outer conductor having two longitudinal slots, the first sections of the inner and outer conductors forming an unbalanced transmission line, and the second section of the inner conductor and the other conductive portion of the outer conductor forming a balanced transmission line of the same characteristic impedance. Fig. 1 shows a connector connecting a signal generator 26 to antennae 25, which is suitable for operation over a wide frequency band. The first section consists of conductors 10 and 12 which may be provided by a normal coaxial cable of any desired length. The second section. consists of conductors 11 and 13, the length of these sections being equal to one quarter of the mean operating wavelength. The outer conductor 11 is divided into two conducting portions 11a and 11b by two' diametrically opposed slots 15. A semicircular conducting member 17 connects the inner conductor 13 to portion 11b. The dipole antennae 25 are connected to 11a and to eonductor 13. In order that the characteristic impedance of the balanced section 11a, 13 shall be equal to that of the unbalanced section 10, 12, the diameter d2 of inner conductor 13 is made equal to the geometric mean of the diameters d1, d0 of the inner and outer conductors 12 and 10. An equivalent circuit is described, in which the arrangement is shown to behave as having a short-circuited quarterwave stub line connected at each end of the second section. For optimum wide-band operation, the characteristic impedance of the stub line across the free end of the second section should be equal to that of the other effective stub line, and also that of the balanced section 11a, 13 of the connector. This may be arranged by appropriately selecting the width of slots 15. The connector may be constructed so as to compensate for impedance changes in the balanced circuit coupled thereto. Flanges extending along the lengths of the slots 15 may be introduced, which reduce the impedance of the stub line effectively connected across the free end of the second section, and thereby compensate impedance changes introduced by a series resonant antenna circuit. In the case of a parallel resonant antenna circuit, the loading of this equivalent stub line may be increased. In a modification (Fig. 6, not shown) the inner conductor 13 has a hollow semicircular cross-section. ' This is shown'to have the effect of increasing the characteristic. impedance of the equivalent stub line connected at the lower end of the second section. The relative dimensions of the conductors in any of the examples may be modified by employing different dielectric materials.
